are you using (Li-ion, LiFePO4, Lead-acid)? What is the voltage of the system (12V, 24V, 48V)? Are you using it for charging or discharging ?
| Problem | Potential Cause | Solution | | :--- | :--- | :--- | | | The connected battery is not within the 6-60V DC range, is faulty, or not connected properly. | Check your battery voltage with a multimeter. Ensure it is between 6V and 60V. Reconnect it firmly to the "Input" or "Output" terminals as per your mode. | | Screen flashes "ERR" | Your "dn" (Lower Limit) parameter has been set to a value higher than your "UP" (Upper Limit) parameter. | Re-enter your parameter settings menu. Correct the values so that the Upper Limit is always greater than the Lower Limit . | | Screen flashes "H:ER" | The charging time (OP) setting is insufficient or unreasonable relative to the battery's state of charge. For example, the set time ran out before the battery could reach the UP voltage. | Press any key to stop the flashing. Increase the charging time value (OP) to allow the battery more time to fully charge. | | Controller not switching | Relay failure or incorrect parameter settings. | Check your UP, dn, and OP settings again. If all are correct but no switching occurs, the relay may be faulty. |
Displays voltage (V), percentage (%), and time (H:M). UP Button: Switched display/increases values. DOWN Button: Toggles output/decreases values. SET Button: Enters parameters/configures mode. xycd60 manual
Concluding note The XYCD60 manual is the definitive source for safe operation and getting the most from your device. Keep a copy accessible (digital or printed) and consult it whenever you perform maintenance or run into issues.
The XY-CD60 features a clean LCD layout and three simple navigation buttons: UP , DOWN , and SET . are you using (Li-ion, LiFePO4, Lead-acid)
Set (Down Limit): The voltage at which the load turns OFF (discharge protection). When battery voltage
The relay closes (powers the load) when battery voltage is above the Upper Limit (UP) . It opens (cuts power) when voltage falls below the Lower Limit (dn) to prevent deep discharge. Setup and Programming | Problem | Potential Cause | Solution |
Crucially, the XY-CD60 on its own; it functions strictly as a smart, programmable relay that connects or disconnects an external charger or load based on real-time voltage measurements. Technical Specifications

The is a highly versatile, microcontroller-based DC 6V–60V battery charge and discharge controller module . Operating primarily as an intelligent voltage-controlled relay switch, the device automates battery protection by preventing overcharging during its charging phase and preventing deep discharge during its depletion phase.
